I found this very well made and very strong. Unfortunately the top mesh pocket didn't last long though. Within a few weeks my sons foot had gone through it and now 8 months later that pocket is no more. It does however have other tougher pockets underneath, shame the top one wasn't made in the same way. The top and bottom pockets aren't very deep, so cant hold big books but fine for small ones. Also the bottom pocket hangs out if anything is put in it, so nothing ever was, because it would just get stood on. The material used for the main part is very tough, and I've bought other types since and none are as tough. Even with its faults its the best of a bad bunch that I've come across.
